Bromination of 6-benzylaminopurine (1) with Br2 in AcOH in the presence of AcONa afforded 6-benzylamino-8-bromopurine (2) in 59% yield. The position of bromination was confirmed by direct transformation of bromide 2 by reaction with NaN3 in dimethylsulfoxide to 8-azido-6-benzylaminopurine (3) in a yield of 70% and comparison of its properties with the known compound 2-azido-6-benzylaminopurine (11)
